Dryer shows F15 and may shut down or not start.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Faulty communication between main control and submodules (e.g., inverter, UI), damaged communication harness, control board failure

Safety first: Disconnect power before accessing electronics.

Check communication wiring:

Remove the top cover and locate the harnesses linking the main control board to other modules (UI, inverter, sensor boards).
Reseat all multi-pin connectors and inspect for bent pins or corrosion.
Look for any pinched or damaged harnesses along their routing.
Perform a power reset and test again.
If F15 remains, one of the electronic modules is likely defective. Professional diagnostic tools are recommended to identify the faulty module.
